My Technology Adventure

Domain account locked out on vCenter Server

That’s a very small problem but it struggles you if you are enterprise datacenter administrator. As you may know the best practices to run application is by service account. But sometimes you may testing applications by your own domain account and forget remove it.

Few days ago, my domain account locked out on domain controller. The audit report indicated it locked out by vCenter Server every 5 seconds. Then I logged in the vCenter Server, checked out Task Scheduler, Services, Task Manager…etc. Nothing was running under my domain account. I stopped applications one by one on the vCenter Server and related plugin services. No help, I felt so frustrated!!!

After the steps above I finally figured out that root cause was my VMware View LAB VM tried to authenticate on vCenter Server by my domain account and stored old password. I powered up the old VM few days ago.
